We have an HP 4200/4300 that has two EIO slots. The JetDirect card that we had installed stopped working (or at least we thought it was the card), but when we took it out and inserted a different, working card, it still didn't respond. Then, after reinserting the original card, it lit up as a 100Mbps connection, even though it was plugged into a 10Mbps hub. Is this more likely a problem with the EIO slots? When we print out the config page, it lists both EIO slots as empty. And, if it is the EIO slot, is that repairable (sp?) ? Thanks in advance!
